Soon(TM) probably. I'm seeing a lot of request so I'll definitely do it.
Any other features you think would be cool to add if I make a post-jam mobile version?
I think i would like it if the pawns worked as real pawns. You know, only farwards and promotion. My guess is that you had the pawns like that but decided it's better if they take to any diagonal direction. My opinion is that they should act like real pawns.
